Primer
Will someone tell me which epoxy primer from PPG to use on my 68. Car is stripped, prepped and I am about ready to start the priming phase. I know to ask the paint supplier but they are pretty young. I am looking for real world advice.. The supplier I've been getting my materials from has been great and works with me but I'm still looking for experienced input.
Thank you.
Thank you.

Seal with epoxy sealer/primer
Prime with high build Finishsand
Block the Finishsand in between coats
What to use for final sealer before base coat?

So after the FinishSand, I blocked it Cleaned it all down and used Axalta Chromax products. I liked the fact that I could talk directly with the tech staff who answered all of my dumb questions. They had the line on what shade of sealer for the War Bonnet yellow from 71. They also suggested the higher degree products for the high heat and humidity here in Florida. No expert, but this worked for me. You have many ways of going and members will let you know what worked for them.
Good Luck in your choice. Oh that was my first metallic job and only the second vette I have painted. Makes me appreciate the folks that do this for a living.

On your 1968 ...there is no need to HAVE TO use epoxy primer. You can simply apply the polyester primer..
On cars that are SMC (which your 1968 is not).....then I DO apply an epoxy primer and I use PPG's DP90LF. The reason I apply an epoxy primer on SMC is due to the polyester primer I use... which has not been the SlickSand...it is seems to aid in linking up to it.

As for the sealer that you choose to apply on top of the polyester primer. It MAY BE wise to contact the paint manufacturer of the paint you plan on shooting and see what they say or offer.
Using PPG's epoxy primer as a sealer or even SPI's epoxy primer as a sealer PRIOR to painting the car should be more than sufficient...BUT....sometimes if by some odd chance you have an issue.....then the paint manufacturer is not going to warranty their product due to you did not use what they specified.
Do I use different brands of materials and have success....YES I DO...but I also know that if I start playing around with switching brands...I am not going to waste my time in trying to get someone to pay for my choices in what I used.

Epoxy Primer + Martin Senour Polyester Primer #5190
Thanks DUB, that answers some of the questions I have been struggling with in the last week: For my '77 I was looking into using the Martin Senour Polyester Primer #5190 which you are familiar with. I did not know if I should first be applying epoxy primer on the bare SMC or not.
I think what you just wrote is that yes, apply epoxy primer first on SMC. Now, I suppose you then apply the Polyester Primer #5190 within the recoating window of the epoxy primer for a chemical bond, as opposed to letting it dry and sanding it for a physical bond, right? Apologies for the intrusion. Thanks!

I think Martin Senour discontinued the 5190....or at least in my area that stopped selling it and now have some new 5192 ( I believe) and I have tried it BUT it is EXPENSIVE as all get out and I WILL NOT use it again and will use another polyester primer. More than likely SlickSand.

Thanks DUB. Good info.
I found these links:
https://www.napaonline.com/en/p/MSTGAL5190 for $221/gal (which in practice does not mean that it is still available).
https://www.napaonline.com/en/p/MSRGAL5192 for $234/gal.
Slick Sand is about half the cost. I may be using it too instead.

Have you tried the Eastwood polyester primer.

Pricing is very attractive.
They also carry the Evercoat brand.

Not saying that it is not a good primer...but I would not buy it ..and possibly have to pay shipping to get it to me and use it....when I can get the name brand stuff locally.
Sometimes when costs of a product get to low...I begin to wonder why it is that way. Now if SlickSand or a major brand had it on sale...that is another thing entirely. kind of like when rebuilt master cylinder may cost $30...and new one is $100. I wonder if the cost savings is worth it when dealing with the brakes of a car. And a primer that we all rely on to do its job kind of falls in that same way of thinking. Is the cost saving WORTH it or not to possible take the chance.
IF I chose to use it I would have to shoot test panels and see how it holds up for quite some time before I would apply it on a customers car.
